1. The hereinfdescnibedmethod of duplicating documents consisting intypewriting' the original d ocumentW-ith a pneumatically operatedtype'wheel typewrit-in'g machine, 1 f

the paper stencil being movedby and simultaneously with the typewheel insuch a inanner that-the distances-of the 'stencihhoies are in a;determined relation to the corresponding distances of the typewheelrevolutions, the perforations advancing in lines across the strip, andanew line of perforations being-"started after every revolution 4 of thetypewheel.

2. The herein described apparatus for duplicat ng document's,comprising, in combination, a pneumatically operated type-' writerhaving a type-wheel and actuated by compressed air, a perforating deviceac'tu ated by compressed air, and serving to make spirallyover itscircumference, and means for enabling thetypewriting machine toduplicatethe original document, the duplicatibnbei'ng effected by colnfiessed air from the said reservoir.

The herein described apparatus for du-' pl1cat1ng documents; comprising,in combination a pneumat cally operated typewriting machine having akeyboard and a typewheel and actuated by compressed air; a perforat ngdevice for-making a perforation striking of each character 'of theoriginal document by thewtypewriter, said perforating device actuated byco1npressedair, vand means'for enabl ng the typewriter to duplicate theoriginal document, said means actuated by compressedjair, and comprisingaboard adapted to be exchanged for the ina paper'stencil"simultaneouslywith the keyboard, said board having keys formed withlperforations, anddiaphragms which close the perforations on the passing of theperforated'stencih I In testimon whereof I have signed my name this 26thspecification 'in' the presence of two subscrib ing witnesses.
